What, exactly, do you find “anti-Catholic”? If you object to Lutherans calling the office of the papacy anti–to-Christ, that is something Lutherans have always believed, conditionally. Where it gets sticky here, is that Lutherans do not mean what other denominations mean when they use that term.
The language from your actual confessional document:
9] Now, it is manifest that the Roman pontiffs, with their adherents, defend [and practice] godless doctrines and godless services. And the marks [all the vices] of Antichrist plainly agree with the kingdom of the Pope and his adherents. For Paul, in describing Antichrist to the Thessalonians, calls him 2 Thess. 2:3-4: an adversary of Christ, who opposeth and exalteth himself above all that is called God or that is worshiped, so that he as God sitteth in the temple of God. He speaks therefore of one ruling in the Church, not of heathen kings, and he calls this one the adversary of Christ, because he will devise doctrine conflicting with the Gospel, and will assume to himself divine authority.
OF THE ANTICHRIST
As to the Antichrist we teach that the prophecies of the Holy Scriptures concerning the Antichrist, 2 Thess. 2:3-12; 1 John 2:18, have been fulfilled in the Pope of Rome and his dominion. All the features of the Antichrist as drawn in these prophecies, including the most abominable and horrible ones, for example, that the Antichrist “as God sitteth in the temple of God,” 2 Thess. 2:4; that he anathematizes the very heart of the Gospel of Christ, that is, the doctrine of the forgiveness of sins by grace alone, for Christ’s sake alone, through faith alone, without any merit or worthiness in man (Rom. 3:20-28; Gal. 2:16); that he recognizes only those as members of the Christian Church who bow to his authority; and that, like a deluge, he had inundated the whole Church with his antichristian doctrines till God revealed him through the Reformation — these very features are the outstanding characteristics of the Papacy. (Cf. Smalcald Articles, Triglot, p. 515, Paragraphs 39-41; p. 401, Paragraph 45; M. pp. 336, 258.) Hence we subscribe to the statement of our Confessions that the Pope is “the very Antichrist.” (Smalcald Articles, Triglot, p. 475, Paragraph 10; M., p. 308.)
We know that our brothers and sisters in Christ exist in the Catholic Church. We know that, in general, the recent popes have been outstanding models for the Christian life.
